Deborah R. Castleman

Deborah Castleman served as Deputy Assistant Secretary of Defense for Command, Control and Communications in the first Clinton Administration. Earlier, she was part of the issues staff (in Little Rock, Arkansas) of the Clinton/Gore campaign, focusing on space, science and technology, and national security issues. Before that, she was a space and defense policy analyst at RAND, and a satellite systems engineer at the Hughes Space and Communications Group.


She later served as vice president of Rosen Motors, a 70-person startup company developing a hybrid-electric powertrain for automobiles. The company, started by the brothers Benjamin and Harold Rosen, ceased operations in late 1997. After that, she, her husband Harold Rosen, and J.B. Straubel formed a company, Volacom, to develop and obtain funding for Harold’s audacious concept to provide internet access via unmanned circling aircraft. Although unsuccessful in obtaining the necessary venture funding, Harold and J.B. patented the new long-endurance hybrid propulsion system that was later licensed to Boeing. After Volacom closed, J.B. Straubel moved on and became a co-founder and Chief Technology Officer at Tesla Motors, a position he holds to this day.

Ms. Castleman holds a B.S. in electrical and electronic engineering from Cal Poly Pomona, an M.S. in electrical engineering from Caltech, and an M.A. in international studies from Claremont Graduate School (now University). From 1974-1977, she served in the U.S. Air Force as an avionics technician for the F-111 aircraft.


She serves on the board of the Santa Monica Canyon Civic Association. She also is a member of the Caltech PMA (Physics, Mathematics and Astronomy), GPS (Geological and Planetary Sciences) and BBE (Biology and Biological Engineering) Chair’s Councils. Ms. Castleman is particularly interested in following scientific research in the areas of energy, geology, biology, astronomy, cosmology and neuroscience.


She was inducted into the Cal Poly Pomona (CPP) College of Engineering “Hall of Fame” in February 2017. She later gave the welcome address at the April 2017 CPP “Femineer” Summit.


In 2008, she became interested in the subject of global warming, and what might be done to address this concern. Over the subsequent years of looking into this issue, her view  — like many other people who have really looked into this issue — has shifted dramatically. She became disillusioned with the Democrats’ position on this and other issues, and is now a Republican! She also supports President Trump.


Ms. Castleman married Dr. Harold A. Rosen (“the father of the geostationary satellite”) in May 1984. He died peacefully at home on January 30, 2017. She is still grieving the loss of this wonderful man and the life they shared. But life goes on…

My TEDx talk

This talk was given on April 27 2017 at Cal Poly Pomona. In it, I attempt to summarize pointers for success and “lessons learned” throughout my life thus far, in the hope of providing inspiration to others. 

The Best Explanation

I found the interviews with key players and the scientific explanations in this video to be one of the best I’ve seen on the subject.

My Favorite Liz Parrish talk

Liz Parrish is the CEO of BioViva, a company formed to (eventually) provide anti-aging gene therapies to humans. She herself underwent, on Sept. 15 2015, a telomerase-inducing gene therapy and a myostatin-inhibitor gene therapy.
